Screens; and we do hereby declare the following to be a full, clear, andexact description of theinvention, such as will enable others skilled inthe art to which it appertains to make and use the same.

This invention relates to improvements in exits for window and doorscreens and has for one of its objectsthe provision of a device of thischaracter which will permit flies and other insects to escape throughthe door or window. screen when crawling thereon.

Another object of this invention is the provision of a plurality offoraminous extensions formed on the screen and which are secured. overrecesses in the door or window frame and later bent into conicalformation having the apexes open and spaced from the outer face of thedoor or window frame so that flies and other insects on the screen mayescape through the conical portion and which flies or insects will beattracted by the light through the apexes of the conical portion. 7 j

A further object of this invention is the provision of a fly exit forwindow screens of the above stated character, which shall be simple,durable and efficient, and which may be manufactured and sold at acomparatively low cost.

WVith these and other objects in view as will become more apparent asthe description proceeds, the invention consists in certain novelfeatures of construction, combination and arrangement of parts as willbe hereinafter more fully described and claimed.

For a complete understanding of our invention, reference is to be had tothe following description and accompanying drawing, in which V Figure 1is a fragmentary front elevation of a fly exit for window screensconstructed in accordance with our invention,

Fig. 2 is a fragmentary horizontal sectional view of the same,

the frame as clearly illustrated in Fi 1.

The recesses 2 extend approximately rom the inner face of the frame andopen outwardly through the outer face. A screen 3 of foraminous materialis secured to the frame 1 by suitable fasteners 4 and has formed uponits upper edge a plurality of for-aminous extensions 5.

The foraminous extensions 5 are formed by cutting the upper edge of thescreen 3 and are secured over the recesses 2 by means of fasteners 6.The extensions 5 after being V secured over the recesses 2 are bent inconical formation to form exits 6 which have their apexes open asillustrated at 7 and spaced from the frame 1 so that flies or otherinsects crawling upon the screen 3 may pass into the recesses 2 andoutwardly through the conical exits 6 and thereby escape. The flies orinsects will be attracted through the exits 6 by the light through theapexes 7 of the conical exits 6.

While we have shown and described the preferred embodiment of ourinvention, it will be understood that minor changes in construction,combination and arrangement of parts may be made without departing fromthe spirit and scope of the invention as claimed.

Having thus described our invention, what we claim is: s

A fly exit comprising a rectangular frame having a plurality of recessesformed in the outer face of its upper end member, said recessesextending approximately from the inner face outwardly through the outerface of said member, foraminous material secured to the side and lowerend members and having its upper end slotted to form a plurality ofextensions positioned over the recesses, said extensions being firstbent into conical shaped portions having their apexes open to formexits, and inclined upwardly and outwardly over the recesses tocooperate with said recesses for formlng comparatively ends bentlaterally to form flanges which are secured to the upper member of the10 frame about said recesses.

In testimony whereof we afiix our signatures in presence of twowitnesses; c v GEORGE L. ZIERLEIN. OLIVER W. ZIERLEIN. Witnesses: A
